🦉 Uncaught Exception

[pubnub-snyk-universal-prd]

This minor version upgrade for undici contains several security fixes that alter how the client handles specific edge cases and malicious server responses. While no APIs are removed, these changes in error handling and validation constitute a behavioral change that warrants verification.

Key Changes:

• v7.30.1 Security Fixes: This version introduces multiple security patches to prevent Denial of Service (DoS) and cache poisoning vulnerabilities.
  • The client will no longer crash on certain TLS renegotiation errors, oversized Content-Encoding headers, or during decompression. Instead, these events are handled as per-request errors.
  • Memory usage is now bounded for the EventSource parser to prevent memory exhaustion from malicious servers.
  • A cache poisoning vulnerability related to cross-origin redirects has been fixed.
• v7.30.0 Fixes: This version includes various bug fixes and performance improvements, such as honoring headersTimeout and better handling of HTTP/2 streams.

Recommendation: While these changes improve security and stability, the new error-handling behavior could affect applications that have logic tied to the previous, less robust error patterns. It is recommended to verify application behavior after the upgrade, particularly in areas involving error handling, decompression, and interaction with cross-origin resources.
